Answer» Solution-----> 1) First we FIND value of AB by MULTIPLYING A and B First we take first row of A and take first column of B and multiplying first term by first term and second term by second term and putting positive sign between them by this we get first term or AB₁₁ of AB 2) Then we multiply first row of A by second column of of B by same PROCESS we get AB₁₂ of AB 3) Then we multiply second row of A to first and second column one by one to get AB₂₁ and AB₂₂ 4) Now I is identity matrix of 2×2 order , we calculate 3I 5) Now we easily calculate AB - 3I , by subtracting corresponing elements , and get the answers |
